Abstract

The present disclosure relates to an image encoding apparatus and method, and an image decoding apparatus and method whereby the encoding efficiency can be improved in Intra-Block Copy (IntraBC). In the present technique, an example in which a picture is divided into four slices (Slice #0 to Slice #3) is shown. In a case where a reference to a different slice was inhibited, an available reference range from a current Coding Tree Unit (CTU) in the Slice #2 was only a part that had been decoded in the Slice #2; for example, the blocks of the Slice #1 could not be referred to. In contrast, in a case of the present technique, the available reference range also includes different slices as decoded (Slice #0 and Slice #1); for example, it is possible to refer, from the current CTU in the Slice #2, to any block of the Slice #1 as shown in FIG. 5. The present disclosure can be applied to, for example, an image processing apparatus.
